Abstract

Activated carbon fiber (ACF) containing Sn nanoparticles were prepared by impregnation and were investigated as a negative electrode material in lithium batteries. The tin particle size was controlled by selecting an ACF with an adequate surface structure. This Sn/ACF composite cycled versus Li metal showed a first discharge capacity as high as 200 mAh g-1 compared to the pristine ACF which showed only 87 mAh g-1. Excellent cyclability with these composites was obtained with ACF BET SSA as large as 2000 m2 g-1 and 30 wt.% Sn.
